EUVD-2026-108781

In the Linux kernel, the following vulnerability has been resolved: namespace: look at the topmost mount for a mount namespace file attachrecursivemnt preallocates a mountpoint for the root of the topmost mount of the source so that a mount that already sits at the destination can be put on top o...

CVE-2026-98986

The Linux kernel contains a vulnerability where fsnotify marks of a mount namespace are removed from an RCU softirq context instead of a process context. This occurs because mnt_ns_tree_remove() hands a reference to call_rcu(), causing fsnotify_mntns_delete() to trigger a BUG by calling a sleepin...

CVE-2026-98985

The Linux kernel is affected by a slab-use-after-free vulnerability in the path_pivot_root() function. The issue occurs because the kernel reads the parents of new_root and the caller's root before verifying if the mounts are in the caller's mount namespace. If new_root is a file descriptor to an...

EUVD-2026-108779

In the Linux kernel, the following vulnerability has been resolved: namespace: check the mounts before reading their parents in pivotroot pathpivotroot reads the parents of newroot and of the caller's root and checks whether they are shared before it checks that either mount is in the caller's...

EUVD-2026-108778

In the Linux kernel, the following vulnerability has been resolved: dcache: don't put a mountpoint on a dentry that's being removed rmdir, unlink and rename call dontmount on the victim and then detachmounts with the victim's inode locked. dolockmount takes the inode lock of the mountpoint and...

CVE-2026-98982

The Linux kernel contains a vulnerability where a pseudo dentry (for pipes, sockets, etc.) can become the root of a mount via a bind mount of /proc/self/fd/. Because these dentries carry DCACHE_NORCU , they are freed immediately by dentry_free(). If a walker accesses the mount via __follow_mount_...

EUVD-2026-108776

In the Linux kernel, the following vulnerability has been resolved: namespace: don't let a pseudo dentry become the root of a mount dallocpseudo hands out dentries for pipes, sockets and other files that are never anyone's child or parent. They carry DCACHENORCU and dentryfree frees them right aw...

EUVD-2026-108775

In the Linux kernel, the following vulnerability has been resolved: namespace: unhash a dentry before detaching the mounts on it unlink, rmdir and rename remove the entry from the filesystem, call detachmounts on the entry with the inode locked and then call ddelete once the inode is unlocked. Th...

EUVD-2026-108773

In the Linux kernel, the following vulnerability has been resolved: namespace: refuse an automount below a mount that is in no namespace It's possible to add autmounts even when the parent mount isn't in the mount namespace of the caller. The only requirement we have is that the parent mount...

CVE-2026-98978

The Linux kernel contains a vulnerability where a locked mount could be prematurely expired. A shrinkable mount could become locked if a user namespace owner moved it beneath a locked mount using MOVE_MOUNT_BENEATH , causing the locked property to move to the bottom mount. This allowed the top mo...

EUVD-2026-108772

In the Linux kernel, the following vulnerability has been resolved: namespace: never expire a locked mount Locked mounts are special. They protect the underlying files and directories from being revealed. doumount refuses to unmount locked mounts but shrinksubmounts doesn't. A shrinkable mount ca...

CVE-2026-98977

The Linux kernel contains a vulnerability where attach_recursive_mnt() incorrectly handles mount locking for automounts when propagated across user namespaces . Because the kernel may use the caller's mount namespace to determine the user namespace, automounts accessed during path lookup can resu...

EUVD-2026-108771

In the Linux kernel, the following vulnerability has been resolved: namespace: handle mount locking for automounts correctly If mounts are propagated across user namespaces, attachrecursivemnt locks every copy of the source mount to protect overmounts from vanishing and revealing the underlying...

CVE-2026-98976

The Linux kernel is affected by a vulnerability where the attach_recursive_mnt() function incorrectly transfers the MNT_LOCKED property. Specifically, it transfers the lock from the top mount to the mount moved beneath it during a MOVE_MOUNT_BENEATH operation. This allows a user namespace owner t...

EUVD-2026-108770

In the Linux kernel, the following vulnerability has been resolved: namespace: keep the lock on a mount that a propagated copy is moved beneath attachrecursivemnt transfers MNTLOCKED from the top mount to the mount that is moved beneath it with MOVEMOUNTBENEATH. This allows the owner of a user...
